Tropical ice clouds validation in Global Storm Resolving Models using active sensor retrievals
2022<p>Tropical ice clouds play an important role in the energy balance of the tropical atmosphere, yet their modeling has been a challenge and feedback from high clouds in climate models is very uncertain. The new generation of Global Storm Resolving Models (GSRM) is capable of resolving convective and mesoscale motions globally, and ...

Intercomparison of global storm resolving (coupled) climate models
2020<p>The DYAMOND (DYnamics of the Atmospheric general circulation Modeled On Non-hydrostatic Domains) project is an intercomparison project for global storm resolving models with horizontal resolutions < 5km. In Phase 0, nine models participated in simulating a 40 day period from August 2016 on.

Stratocumulus variability in global storm-resolving models
Stratocumulus clouds are important for the Earth's planetary albedo and play a central role in determining Earth's sensitivity to forcing. Recent global-coupled simulations at kilometer-scale resolution in the atmosphere and the ocean, conducted in the framework of the H2020 nextGEMS project, offer opportunities to study cloud processes, their ...Ian D'Amato Dragaud +5 more

Getting a single tropical rainbelt in a global storm-resolving model
Resolving deep convection using a horizontal grid spacing of 10 km or finer was supposed to produce a correct representation of tropical precipitation. Global coupled or uncoupled storm-resolving simulations using the ICOsahedral Non-hydrostatic model (ICON) show a proper representation of the tropical rainbelt over land. However, the tropical rainbeltHans Segura +13 more

A Causal Intercomparison framework unravels precipitation 1 drivers in Global Storm-Resolving Models
Correctly representing convective precipitation remains a long-standing problem in climate models, due to its highly parameterized nature and unclear role of drivers interacting over a wide range of spatial scales. We analyze and compare simulations of Global Storm-Resolving Models, namely the DYAMOND models, using a methodology based on dimensionalityRicard, Lucile +3 more

2023
With global storm-resolving models (SRMs) a new type of global high-resolution models is now becoming available that explicitly resolves the main drivers of the atmospheric flow of matter and energy on the kilometer scale. In these models, arguably two poorly constrained physical processes remain unresolved  - microphysics and turbulence - but

EarthCARE's Potential to Evaluate a Global Storm-Resolving Model Using a Satellite Simulator
EarthCARE, equipped with a suite of passive and active sensors, including Cloud Profiling Radar (CPR), Atmospheric LIDar (ATLID), Multi-Spectral Imager (MSI), and Broad Band Radiometer (BBR), is designed for comprehensive studies of clouds, aerosols, precipitation, and their radiation impact.Woosub Roh, Masaki Satoh

Abstract This study compares the characteristics of global mesoscale convective systems (MCSs) simulated in a global storm-resolving model (GSRM) and a high-resolution (∼25-km) general circulation model (GCM), both developed at the Geophysical Fluid Dynamics Laboratory.
